Metformin Restores Mitochondrial Function and Neurogenesis in POLG Patient‐Derived Brain Organoids

open access: yesAdvanced Science, EarlyView.
Patient‐derived POLG‐mutant cortical organoids reveal neuronal subtype‐specific mitochondrial and synaptic defects, with dopaminergic neurons most affected. Metformin treatment restores neuronal identity, mitochondrial function, and excitability, increased mtDNA maintenance, and reprogrammed metabolism via TCA and redox pathways.
